Reaction scheme:
0x58bGwhPS

Synthesis:
1. A solution of 1H-pyrrolo[2, 3-b]pyridine-3-carboxylic acid (0.49 g, 3 mmol), oxalyl chloride (0.6 mL, 7.2 mmol), and DMF (1 mL) in dichloromethane (20 mL) was stirred for 20 min.
2. The mixture was evaporated and then redissolved in methanol (20 mL) and stirred for 40 min.
3. The mixture was evaporated and then extracted with ethyl acetate.
4. The organic phase was washed with saturated sodium bicarbonate solution and dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.36 g, 68%).
5. A solution of Step 4 (0.36 g, 2 mmol), potassium t-butoxide (0.27 g, 2.4 mmol), and 1-bromo-5-fluoropentane (1.6 g,9.5 mmol) in THF (20 mL) was stirred for 24 h.
6. The mixture was extracted with ethyl acetate.
7. The organic phase was washed with brine and dried with Na2SO4, and the solvent was removed in vacuo.
8. The residue was purified by silica gel chromatography with stepwise gradient elution of n-hexane/ethyl acetate (3:1–2:1–1:1, v/v) to yield the white solid (0.35 g, 65%).
9. A solution of step 8 (0.35 g, 1.3 mmol) and 6 mol/L sodium hydroxide solution (10 mL) in methanol/THF (2:1,v/v, 15 mL) was stirred for 1.5 days.
10. The mixture was evaporated, added to water, and then washed with ethyl acetate.
11. A solution of 1 mol/L hydrochloric acid was added to the aqueous phase, and the mixture was extracted with ethyl acetate.
12. The organic phase was washed with brine and dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.39 g, quant.)
13. A solution of step 12 (0.39 g, 1.3 mmol), oxalyl chloride (3 mmol), and DMF (1 mL) in dichloromethane (12 mL) was stirred for 10 min.
14. The mixture was evaporated and then redissolved in dichloromethane (10 mL).
15. Cumylamine (2 mmol) and triethylamine (0.5 mL) were added to the solution and stirred for 15 h.
16. The mixture was evaporated and then extracted with ethyl acetate.
17. The organic phase was washed with 0.1 mol/L hydrochloric acid solution, saturated sodium bicarbonate solution and brine, and then dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.37 g, 77%).

"Temel kural" olarak her şeyi 370x (1000g/0.37g = 370 oran) ile çarpın.

Elbette bazı çözücülerin daha yüksek yoğunluklu karışıma izin verdiğinden eminim, örneğin 370 kat daha fazla etil asetata ihtiyacınız olmayacak, ancak çözelti aşırı doygun olduğunda hızlı bir şekilde fark edersiniz, ancak daha fazla ısının daha fazla doygunluğa izin verdiğini unutmayın (nedeninden emin değilim).

Bunun için teşekkürler, minnettarım. Ama acemiyim ve hatalardan kaçınmak için özel bilgilere ihtiyacım var.

Merhaba, bu 5F-CUMYL-PEGACLONE (5F-SGT-151) analoğu mu?
Bunun bir sentezini de yüklemeyi düşünüyor musunuz? Bu çok ilginç olurdu.
Muazzam çalışmanız için teşekkür ederim.

Şimdi fark ettim, 5F-SGT-151'in tabanı 3. bir benzen halkası içeriyor. İsimlendirme yükleniyor.
5F-SGT-151'in hazırlanıp 1-bromo-5-fluoropentan yerine kuyruk olarak kullanılıp kullanılamayacağını merak ediyordum,
1-bromo-6-florohekzan kullanabiliriz. Bu bize daha da büyük reseptör afinitesi / etkileri sağlar mı?

Bu verilere göre evet diyebilirim ama bu sadece bir hipotez.

Evet, sanırım bu yeterli olacaktır. Başka bir sorum daha var. En güçlü kannabinoidler hangileridir?

I am interested in the synthesis of 5F-adb is there a simple reliable recipe?
